Description
Изобретение относится к новому процессу изготовления (22R, S)-16α, 17α-бутилидендиокси-11β, 21-дигидроксипрегна-1,4- диен-3,20- диона(будезонида)
(I) путем реакции 11β, 16α, 17α, 21-тетрагидроксипрегна-1,4-диен- 3,20-диона (16α-гидроксипреднизолона)
(II) с бутаналом СН3СН2СН2СНО в среде растворителя в присутствии кислотного катализатора.The invention relates to a new manufacturing process for (22R, S) -16α, 17α-butylidenedioxy-11β, 21-dihydroxypregna-1,4-diene-3,20-dione (budesonide)
(I) by the reaction of 11β, 16α, 17α, 21-tetrahydroxypregna-1,4-diene-3,20-dione (16α-hydroxyprednisolone)
(II) with butanal CH 3 CH 2 CH 2 CHO in a solvent medium in the presence of an acid catalyst.
В соответствии с известным процессом, сущность которого раскрывается в [3] будезонид изготавливается путем реакции 16α-гидроксипреднизолона с бутаналом в диоксане в присутствии хлорной кислоты в качестве катализатора. Продукт реакции выделяют путем разбавления прореагировавшей смеси в хлориде метилена, нейтрализации посредством промывки в водном карбонате калия и воде и испарении растворителя с последующим процессом кристаллизации из эфира-лигроина. Затем продукт очищали посредством хроматографии, например, на установке "Сефадекс". Главные недостатки диоксана заключаются в его способности проникать сквозь защитные покрытия на кожу, образовывать перекиси. Другим недостатком известного процесса является применение хлорной кислоты, являющейся сильным окислителем, в результате чего ее применение в качестве катализатора сказывается в ухудшении качества выделения продукта реакции, а это затрудняет и удорожает последующий процесс очистки и обработки продукта. In accordance with the known process, the essence of which is disclosed in [3], budesonide is prepared by reacting 16α-hydroxyprednisolone with butanal in dioxane in the presence of perchloric acid as a catalyst. The reaction product is isolated by diluting the reacted mixture in methylene chloride, neutralizing it by washing in aqueous potassium carbonate and water and evaporating the solvent, followed by crystallization from ether-naphtha. The product was then purified by chromatography, for example, at a Sephadex unit. The main disadvantages of dioxane are its ability to penetrate protective coatings onto the skin and form peroxides. Another disadvantage of the known process is the use of perchloric acid, which is a strong oxidizing agent, as a result of which its use as a catalyst affects the quality of the isolation of the reaction product, and this complicates and increases the cost of the subsequent process of cleaning and processing the product.
Цель изобретения состоит в том, чтобы создать новый процесс, дающий более качественную реакцию выделения продукта и обеспечивающий более простую и более экономичную обработку и очистку продукта. The purpose of the invention is to create a new process that gives a better reaction of the selection of the product and provides a simpler and more economical processing and purification of the product.
Цель достигается тем, что процесс по изобретению осуществляется в ацетонитриле, а в качестве катализатора применяется р-толуолсульфокислота. The goal is achieved by the fact that the process according to the invention is carried out in acetonitrile, and p-toluenesulfonic acid is used as a catalyst.
Сочетание менее основного (по сравнению с диоксаном) растворителя ацетонитрила и обеднителя, например n-толуолсульфокислоты, дает более качественную реакцию выделения, упрощает и удешевляет процесс обработки и очистки продукта реакции по сравнению с известным процессом, в котором применяются диоксан и хлорная кислота. The combination of a less basic (compared to dioxane) solvent of acetonitrile and a depletion agent, for example, n-toluenesulfonic acid, gives a better reaction of isolation, simplifies and reduces the cost of processing and purification of the reaction product in comparison with the known process in which dioxane and perchloric acid are used.
Согласно предпочтительному примеру осуществления данного изобретения реакцию останавливают путем добавления воды и корректировки должным образом рН реагирующей смеси. Это можно сделать и путем добавления в воду водного карбоната гидрогенизованного натрия. После этого продукт кристаллизуется. Кристаллы отфильтровывают, растворяют в хлориде метилена и метаноле, а затем кристаллизуют путем добавления подходящего углеводорода типа лигроина, гексана, циклогексана или гептана, получая неочищенный продукт, который затем рекристаллизуется в метаноле воде с целью получения чистого будезонида. According to a preferred embodiment of the invention, the reaction is stopped by adding water and adjusting the pH of the reaction mixture appropriately. This can also be done by adding aqueous hydrogenated sodium carbonate to the water. After that, the product crystallizes. The crystals are filtered off, dissolved in methylene chloride and methanol, and then crystallized by the addition of a suitable hydrocarbon such as naphtha, hexane, cyclohexane or heptane to give a crude product, which is then recrystallized in methanol with water in order to obtain pure budesonide.
Процесс изготовления будезонида по изобретению состоит, таким образом, из двух стадий. The manufacturing process of the budesonide according to the invention thus consists of two stages.
Стадия 1. Изготовление неочищенного будезонида. Stage 1. The manufacture of crude budesonide.
16α-гидроксипреднизолон реагирует с бутаналом в ацетонитриле. В качестве катализатора добавляют n-толуолсульфоновую кислоту. Реакционную смесь разбавляют водой и водным карбонатом гидрогенизованного натрия. После охлаждения до 5-15оС кристаллизовавшийся продукт отфильтровывают и промывают водой. Затем влажную или сухую среду фильтрата растворяют в хлориде метилена. Если вещество используется во влажном виде, то образовавшуюся при растворении водную фазу удаляют. Добавляют метанол и осаждают результирующий неочищенный будезонид путем добавки лигроина или другого подходящего углеводорода (например, гексана, гептана или циклогексана), после чего неочищенный будезонид отфильтровывают.16α-hydroxyprednisolone reacts with butanal in acetonitrile. As a catalyst, n-toluenesulfonic acid is added. The reaction mixture was diluted with water and aqueous hydrogenated sodium carbonate. After cooling to 5-15 ° C., the crystallized product is filtered off and washed with water. The wet or dry filtrate medium is then dissolved in methylene chloride. If the substance is used in wet form, then the aqueous phase formed during dissolution is removed. Methanol is added and the resulting crude budesonide is precipitated by the addition of naphtha or other suitable hydrocarbon (e.g. hexane, heptane or cyclohexane), after which the crude budesonide is filtered off.
Стадия 2. Изготовление чистого будезонида. Stage 2. Production of pure budesonide.
Неочищенный будезонид растворяют в метаноле при температуре около 60оС. Раствор фильтруют сквозь плотный фильтр и кристаллизуют продукт путем добавки воды. После охлаждения до температуры 5-20оС, фильтрации и промывки в метаноле воде, будезонид сушат в вакууме при температуре 40-45оС. Этот процесс проще, гораздо экономичнее и менее опасен для здоровья, чем известный процесс.The crude budesonide is dissolved in methanol at a temperature of about 60 about C. The solution is filtered through a dense filter and the product crystallizes by adding water. After cooling to 5-20 ° C, filtering and washing with methanol in water the budesonide is dried in vacuum at 40-45 C. This process is simpler, more economical and less hazardous to health than known process.
Рабочий пример. Реакцию выполняют в атмосфере азота. 15,4 г n-толуолсульфоновой кислоты растворяют в 200 мл ацетонитрила. В раствор добавляют 50,0 г 16α-гидроксипреднизолона и 17,6 мл бутанала. Температура увеличивается до 25оС. Через 30 мин растворяется большинство материала. Вскоре после этого продукт начинает кристаллизоваться. Через 3 ч реакцию останавливают путем добавления 75 мл насыщенного водного раствора карбоната гидрогенизованного натрия, в результате чего кристаллизуется продукт. Высушенный продукт растворяют в хлориде метилена и метаноле и кристаллизуют путем добавления лигроина (барометрическое давление 40-65), получая неочищенный будезонид.Working example. The reaction is carried out in a nitrogen atmosphere. 15.4 g of n-toluenesulfonic acid are dissolved in 200 ml of acetonitrile. 50.0 g of 16α-hydroxyprednisolone and 17.6 ml of butanal are added to the solution. The temperature rises to 25 about C. After 30 minutes, most of the material is dissolved. Soon after, the product begins to crystallize. After 3 hours, the reaction is stopped by adding 75 ml of a saturated aqueous solution of hydrogenated sodium carbonate, whereby the product crystallizes. The dried product is dissolved in methylene chloride and methanol and crystallized by the addition of naphtha (barometric pressure 40-65), obtaining the crude budesonide.
Неочищенный будезонид рекристаллизуют из метанола воды, получая чистый будезонид с соотношением изомеров A B≈1 1 (определено методом жидкостной хроматографии высокого давления), [α] 25 100,0о (с 0,2; СН2Cl2); M+ 430 (теоретическое значение 430,5).The crude budesonide is recrystallized from methanol of water to obtain pure budesonide with an isomer ratio of AB≈1 1 (determined by high pressure liquid chromatography), [α] 25 100.0 about (with 0.2; CH 2 Cl 2 ); M + 430 (theoretical value of 430.5).
